Why is threat intelligence better than SIEM data?
A threat intelligence platform automates the processing and analysis of data from multiple feeds improving SIEM security. This relieves staff overload by providing them with an effective means of analysis in real-time. Security teams can thus respond more quickly and accurately to threats.
Why does the organization need SIEM use cases?
SIEM is a vital part of threat detection. Use cases created should detect indicators of compromise, malware infections, and system vulnerabilities. Look for activities that suggest malware like unusual network traffic spikes and traffic queries to known malware domains and IP addresses.
What is a SIEM alert?
